Why this score?
Four weighted factors drive the Marion County risk score. Methodology is fully documented — each input is public data or a reasoned proxy.
Limited in-county generation, but adjacent counties have significant capacity.
St. Johns River WMD — mixed urban/rural, moderate capacity.
Suburban. Some large parcels available, but growing competition.
One adjacent county has an active project. Regional infrastructure is already being tapped.
Water infrastructure
Any hyperscale data center in Marion County would need a consumptive use permit from the St. Johns River (split with Southwest Florida) Water Management District. Marion County is split between two water management districts, which can trigger dual-agency review for a project straddling the internal district line.
The St. Johns River Water Management District covers 23% of Florida's land area and serves roughly 4.7 million residents across northeast and east-central Florida. Average daily water use hit 1.49 billion gallons in 2023. The district declared a Phase 1 Moderate Water Shortage in February 2026 affecting parts of Alachua, Baker, Bradford, Marion, and all of Duval County.
A single hyperscale data center using evaporative cooling can require 1–5 million gallons per day. With the district under an active Phase 1 Water Shortage declaration in early 2026, any new consumptive use permit for millions of gallons per day faces a much higher bar than in a normal water year.
Electric infrastructure
Grid capacity and transmission access are the single biggest driver of where hyperscale developers actually site projects.
Marion County has an unusually diverse utility mix. Duke Energy Florida serves the majority of customers, with SECO Energy, and City of Ocala Electric covering cooperative and municipal territory within the county. Major horse country; Duke's Marion-Levy-Alachua transmission upgrade runs through here.
Duke Energy Florida is the state's second-largest investor-owned utility. Duke has been actively upgrading transmission capacity in central and north Florida to handle growing industrial demand — the Fort Meade hyperscale project in Polk County is tied to Duke's Hines Complex.
Adjacent county activity
Data center campuses tend to cluster near existing infrastructure, meaning proposals in adjacent counties can quickly change the risk picture for Marion County.
State legislative context
Florida's 2026 legislative session produced the regulatory framework that will shape every data center proposal in the state, including any that may come to Marion County.
Florida's 2026 legislative session produced multiple bills that directly affect how data centers can be sited and permitted statewide, including in Marion County. HB 1007 and SB 484 both propose restrictions on hyperscale data center siting, mandatory impact studies, minimum setbacks from residential areas and schools, and water-use disclosure requirements. Neither bill bans data centers outright — they raise the procedural bar. Some versions would allow economic development agencies to shield the end-user identity of a project for up to 12 months after filing, a provision that has already been used at projects like Project Tango in Palm Beach County.
No active data center in Marion County — yet.
Palm Beach got four days notice before their first zoning vote. Citrus County is drafting guidelines on Holder Industrial Park's 813-acre expansion. What they did, you can do — but only if you're ready before the proposal lands.
